The first thing to try is to turn the machine off, then back on at the red "main power" switch located on the left side of the machine. If the code returns it is indicative of firmware problems or a loose connection.
At this point I would seriously recommend getting a service tech to come out. However, if you want, you can take off the back cover (MAKE SURE THE POWER CORD IS UNPLUGED) and double check all of the connections by (GENTLY) pressing them into their connections. Hope this helps. Let me know.
